The Intel 285K CPU in my high-end 2025 Linux PC died again! 😡 Notably, this was the replacement CPU for the original 285K that died in March, and after reading through the reviews of Intel CPUs on my electronics store of choice, many of which (!) mention CPU replacements, I am getting the impression that Intel’s current CPUs just are not stable 😞. Therefore, I am giving up on Intel for the coming years and have bought an AMD Ryzen 9950X3D CPU instead.
Why? It’s designed to run up to 105c.
I think it was when AMDs 7000 series CPUs were running at 95c and everyone freaked out that AMD came out and said that the CPUs are built to handle this load 24/7 365 for years on end.
And it’s not like this is new to Intel. Intel laptop CPUs have been doing this for a decade now.
CPUs should throttle as they approach the limit to prevent thermal runaway. As it gets closer to that limit, it should adjust the frequency in smaller increments until it arrives at that temp to keep the changes to temps small.
105c is the max operating temperature. It’s not going to run away the second it hits 106.
Your CPU starts throttling at 104c so that way it almost never hits at 105c for long If it can’t maintain clocks then it drops them until 104c can mostly be maintained.
If you have an improperly mounted cooler, you could very well get to 105C incredibly quickly, and 115C or whatever the halt temp is shortly after.
